Dear all,
I have a problem
r3, r4,r5 are 3 frame relay routers with r3 as the hub, dlci to ip mapping
didnt support broadcast
and you want to enable multicast on the 3 routers
tunnels will be the sollution, I make twon tunnels over the frame relay
cloud ( tunnel 34 and tunnel 35 ), the first between r3 and r4 and the
second between r3 and r5
r5 will be a backup to r4 in case there is a failure.
I try to use anycast rp and I configure it with no problem, the anycast rp
will be 150.1.9.9.
the problem that I try to use floating mroutes on r3 from 150.1.9.9 ( in
case tunnel 34 is down, mcast traffic will flow to tunnel 35).
but when I do that the mroute replaced each others
here is the configuration on R3
interface Tunnel35
ip address 154.1.35.3 255.255.255.0
ip pim sparse-mode
tunnel source Serial1/0
tunnel destination 154.1.0.5
!
interface Tunnel34
ip address 154.1.34.3 255.255.255.0
ip pim sparse-mode
tunnel source Serial1/0
tunnel destination 154.1.0.4
!
!
interface Serial1/0
ip address 154.1.0.3 255.255.255.0
encapsulation frame-relay IETF
ip ospf network point-to-multipoint non-broadcast
serial restart-delay 0
frame-relay map ip 154.1.0.4 304
frame-relay map ip 154.1.0.5 305
frame-relay interface-dlci 304
frame-relay interface-dlci 305
no frame-relay inverse-arp
frame-relay lmi-type ansi

Rack1R3#sh ip route 150.1.9.9
Routing entry for 150.1.9.9/32
Known via "ospf 1", distance 110, metric 20, type extern 2, forward metric

!
now i try to configure floating mroutes
Rack1R3(config)#ip mroute 150.1.9.9 255.255.255.255 tunnel 34
Rack1R3(config)#ip mroute 150.1.9.9 255.255.255.255 tunnel 35 200
but what happend is that the last command override the first one as shown
Rack1R3#show startup-config | i ip mroute
no ip mroute-cache
ip mroute 150.1.9.9 255.255.255.255 Tunnel35 200
Rack1R3#
Rack1R3#
Rack1R3#sh ip rpf 150.1.9.9
RPF information for ? (150.1.9.9)
RPF interface: Tunnel35
RPF neighbor: ? (154.1.35.5)

Please help
thanks in advance
